Has a body, neck, and head.

Trochlea of the talus

Pulley that is formed by the dorsal surface of the body. Articulates with the crural bones to form the talocrural joint.

Superior surface is continuous MED with commashaped facet for medial malleolus. Laterally with a triangular facet for the lateral malleolus.

Posterior process fo trochlea

Posterio surface. Larger lateral and medial tubercle deparated by a groove containing the tendon of the FLEX hallucis longus

Subtalar joint

Formed by the plantar surface covered with an oval concave facet that articulates with the convex posterior talar facet of the calcaneus

Neck of the talus

connects the body to the head

Sinus tarsi

A canal between the neck and the calcaneus

filled by the interosseous talacalcanean ligament

Head of talus

articulates in fron with concave proximal articular surface of navicular and below with the upper surface of the spring ligament and the ANT and middle talar facts of the calcaneus to for talocalcaneonavicular joint
